AbstractIn this study, the CoCrW-xCu alloys (x= 2, 3 and 4 wt%) were fabricated using selective laser melting (abbreviated as Co-2Cu, Co-3Cu and Co-4Cu) with the purpose of reducing the inflammation responses and the activity of osteoclast. The metal ions releasing test showed that when the Cu content was less than 4 wt%, the releasing amount of Co and Cr ions was very small; however, when 4 wt% Cu was added in the CoCrW based alloy, the quantity of Co ions was significantly elevated with respect to the other groups due to the segregation of precipitates in the matrix; the Cu2+ ion quantity of the Co-2Cu, Co-3Cu and Co-4Cu alloys were 0.05, 0.09 and 0.27 mu g/(L cm(2)) after 7 d immersion, respectively; the RT-qPCR and ELISA data indicated that the expression levels of the pro-inflammatory cytokines (TNF-alpha and IL-6) were down-regulated in the Co-3Cu and Co-4Cu groups, whereas the expression level of the anti-inflammatory cytokine (IL-10) was up-regulated in all CoCrW-xCu alloys; meanwhile, the Cu-containing CoCrW alloys significantly down-regulated the expression of the NF-kappa B signal pathway in a Cu content-dependent manner, and the downstream transcription factors of NF-kappa B signal pathway including NFATc1, TRAP and Cath-K were also down-regulated via potentially manipulating the NF-kappa B signal pathway. After comprehensive consideration, it is considered that the Co-3Cu alloy is a potential material for self-alleviating inflammatory responses.
